JAMES A. CAMERON, OF BROOKLYN, NEW YORK, ASSIGNOR ,TOQOAMERON MA HINE COMPANY, OF BROOKLYN, NEW YOR A C POR TIO on EW YORK FRICTION RESISTANCE DEVICE-EORHVWIVNDING MACH NES j] Application filed October 25, 1928. Serial NO. 314,860. r

This invention relates to winding machines for webs of flexible material, and has for its main object the production of means whereby coils of flexible material may be so wound as to have such difi'erent characteristics of hardness as may be desired under difierent conditions or with different materials.

In an application filed July 28, 1926, Ser. No. 125,350, now Patent No. 1,707 ,047 is disclosed a winding machine in which the rise of a member, displaceable by the accumulation of wound material, is opposed at a diminishing rate by certain instrumentalities of which two examples, one a counterweighting means and the other a friction means as sociated with a carriage and guides, are shown. The present application is a continuation in part of the previously-mentioned application in that it is directed specifically to the friction means associated with the carriage and guides.

In the accompanying drawings the inven* tion is disclosed in several concrete and preferred forms in which:

Fig. 1 is a somewhat diagrammatic view in side elevation of a winding machine embodying the invention;

Fig. 2 is a view, artly in elevation and partly in section, 100 ring in the directlon of arrow 2 of Fig. 1;

Fig. 3 is a sectional view substantlally on the plane of line 3-3 of Fig. 2;

Fig. 4 is a sectional view substantially on the plane of line 44: of Fig. 2;

Fig. 5 is a detail view similar to Fig. 2 but showing a modified form of the invention; and

Fig. 6 is a sectional view substantially on the plane of line 6-6 of Fig. 5.

The winding means may be of widely different types but as here exemplified by drums 1 and 2. The member displaceable by.

the accumulation of materialmay be either winding shaft 3 or top pressure roll 4, but the invention is here exemplified by applying it to the top pressure roll. As here shown, the top pressure roll and its carriage 34 arecarried by flexible connections 6 and counterweighting means 7 the connections passing here over sprocket wheels 8 and the. counterweightin'g means sliding on inclined ways:9. Carriage 34 slides on guides 35 of the framework, and associated with the guides and carriage are means to resist the movement of displacement of said carriage with respect to said guides. As here shown, these means ance to the displaceable member, here the 1 top pressure roll, as it rises in response to an increase in the amount of wound materialon the winding shaft. It will further be understood that the-shape of surface 237 will determine the amount ofresistance Offered to the rise of the carriage, andthat thiscan be varied by having differently shaped surfaces. In the present instance, the resistance decreases as the top pressure-roll rises. H

.In Figs-5 and 6 is showna modification. of this invention in that brakesurfaces 37 are pivotally supported at 39 and are normally urged outward by springs 40, there being an adjustment screw 41 to adjust theamount of taper desired. H L
